NEW YORK (CBS) Juan Carlos Portieles, aka DJ Seasunz, the popular Miami disc-jockey who police say confessed to killing his college freshman girlfriend, Jaclyn Elisse Torrealba, surrounded himself with underage girls at clubs, where he bought them drinks and flirted with them, according to his friends.

Jaclyn Torrealba's family found the relationship between their teenage daughter and the 30-year-old disc-jockey "disturbing," according to the teen's cousin, Daniela Torrealba, who spoke with Crimesider via telephone Monday night. The family had "issues because he was so much older" she said.

Jaclyn Torrealba was apparently in high school and a minor when the two began dating, according to Portieles' arrest warrant, which states the two dated for about two years.

Erika Escobar, 22, who met Portieles "through the club scene" when she was 17 years old, said she found him "slightly odd and sometimes creepy," in an email to Crimesider.

Portieles also bought drinks for underage girls he met at clubs, Escobar said in an email.

According to a 17-year old who worked with him selling tickets to a music festival, Portieles was adored by young girls. These teens "LOVED" the popular DJ and "thought he was sweet and charming," the teen, who asked to be called "Juliette," said in an online interview with Crimesider.

Portieles would go to "all the clubs that 15-25 year olds go to," and that "all he had was younger girls," Juliette said.

"Juliette" also said that Portieles "drank a lot."

Jaclyn Torrealba was 18 years old and a freshman at Florida International University when she and Portieles got into a dispute which ended in her death, according an Oct. 12 arrest report from the Miami-Dade police, which also says that Portieles drove around town with her body in the passenger seat of his car after he killed her.

Friends described Jaclyn Torrealba as a teen who loved to have fun and party, but who also managed to find balance in her life and dedicate herself to her studies.

"She knew how to balance school and night life," Andres Tamayo, a high school friend, told Crimesider. "She was a party animal … and an awesome friend," he said.

Her father, Pablo Torrealba, wrote on his daughter's Facebook page, confirming her death to friends who had been worried about the teen since she went missing Sunday, Oct. 11. Pablo Torrealba wrote, "My sweet little princess, so much joy you gave me with every smile, so much happiness with every hug, so much love with every gaze ... you will forever be with us."

Daniel Torrealba says her cousin "never talked about [Portieles]" with her family.
